 # PEtab changelog

+### 0.4.0
+
+**Prepare for PEtab v2**
+To enable ongoing support for PEtab v1, while "forking" the v1 code for PEtab v2, the old code base is now available at `petab.v1`, and the new code base will be at `petab.v2`. For now, old `import petab.*` statements still work, but are marked as deprecated, and `import petab.v1.*` should be used instead. `petablint` will be designed for use with only full PEtab problems in future too, rather than individual tables -- partial problems will be supported to validate individual tables.
+
+* Add PEtab math parser and sympy converter by @dweindl in https://github.com/PEtab-dev/libpetab-python/pull/260
